LEVEL.

SPECIFICATION forming part of Letters Patent No. 655,326, dated August 7, 1900.

Application filed April 5, 1900i Serial No. 11,689. (No model.)

To @ZL whom t may concern:

Be it known that I, SAM M. COMES, a citizen of the United States, residing at Mount Sterling, in the county of Montgomery and State of Kentucky, have invented a new and useful Level, of which the following is a specification.

This invention relates to levels, and has for its object to provide an improved plumblevel and clinometer in which the parts thereof are effectually housed within the stock of the instrument and the index is arranged to be conveniently seen at opposite sides of the stock. It is furthermore designed to arrange the pivotal supports of the index so as to form guides therefor to conveniently indicate the perpendicular position of the index when the stock is placed upon either end or when resting upon either edge.

Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of a level constructed in accordance with the present invention. Fig. 2 is a central transverse sectional view thereof.

Corresponding parts in both iigures of the drawings are designated by like characters of reference.

Referring to the drawings, l designates the stock of the instrument, which is preferably formed of wood, as usual, and provided with a central transverse circular opening within which the index and other parts of the device are mounted. At the center of the opening there is provided an annular shoulder 2, against which is secured an index -ring 3, which is graduated upon opposite sides, so as to be seen from opposite sides of the stock. In the opposite sides of the stock and surrounding the central opening therein are the sockets or recesses 4 for the reception of the glass covers or crystals 5, which are'iush with the adjacent sides of the stock and are de-` signed to protect the operating parts of the level and at the same time to permit of them being seen. These glass covers are held in place by suitable headed fastenings 6, which are driven into the stock, so that their heads may overlap the glasses.

Located at opposite sides of the stock and extending diametrically across the respective ends of the transverse opening therein are the bars or arms 7, which are disposed at right angles to each other, one longitudinally of the stock and the other transversely thereof. Each end of each arm or bar is provided with a flat laterally-enlarged head 8, which is let in ush with the back of the adjacent recess 4, in which the glass cover is seated, and is secured by means of a suitable fastening 9. Located within the index-ring is the pointer or index IO, which is provided with a suitable Weight ll at Aone end and is also provided with a central transverse spindle or axis 12, which has its opposite ends pointed and journaled in suitable sockets formed in the inner sides of the respective bearing arms or bars '7, as best shown in Fig. 2 of the drawings.

From the foregoing description it will be apparent that the parts of the level are few in number and are conveniently assembled, so as to be in compact relation and easily seen from opposite sides of the stock, also by reason of the right angled disposition of the bearing or supporting arms for the pivotal index the latter will be alined with one or the other of the arms when in a vertical position, so that said arms form guides to convenientl y indicate the vertical position ofthe index whether the stock be stood upon either end or upon either edge thereof.

What is claimed is- Alevel, comprisinga stock, having an open; ing formed transversely therethrough,a scalering fixed within the opening and substantially midway between the opposite faces of the stock, opposite arms extending diametrically across the opposite ends of the opening and disposed at right angles to each. other, one of the arms extending longitudinally of the stock, and the other arm extending trans- ICO versely thereof, and a pointer located Within my own I have hereto affixed 1n y signature in the piane of the scale-ring and having an inthe presence of two Witnesses. termediate s indle the o osite ends of which are mounte) in the ingr faces of the re- SAM M COMES' spective arms, the latter also foi-mini.,r guides Witnesses: for alinement Withihe pointer. MILLARD R. HAINLIN,

In testimony that I claim the foregoing as M. C. MOKEE.
